Happy First Birthday, CRS-3!

April 11, 2011 - 6 Comments

Can you believe it? It’s been one year since we launched the Cisco CRS-3 Carrier Routing System! I’m very pleased that the CRS-3 adoption rate is four times faster than the original CRS-1 series. In just a year, 80 service provider customers in more than 30 countries are deploying the platform – a true testament to the scalability and sustainability of the architecture.

Further, service provider customers across the world like AT&T, Comcast, Turkcell in the Middle East, Main One in West Africa, and Hong Kong Broadband in East Asia, among others, are unanimous about the CRS platform increasing the relevance of the network by enabling fixed-mobile convergence, value-added services and consumer broadband. We appreciate the vision and innovation demonstrated by our customers as they incorporate the CRS-3 platform into their next-generation networks.

The strong market response to the CRS-3 validates our belief that this platform is the foundation for the next-generation Internet.   Unlike competitive offerings that require refreshers, upgrades or even full replacements within just a few years, the Cisco CRS platform is designed to seamlessly accommodate the extraordinary growth of video traffic, mobile devices and new online services through this decade and beyond, delivering unprecedented investment protection.

While others in the industry make promises of 100G, we are shipping more capacity than all of our competition combined.  The CRS-3 and IOS XR engineering teams are bringing to market truly world class innovations in all aspects of design, development and delivery. I am very proud of the CRS development team.

  1. This is a great progression for a platform that was launched only a year ago. That goes to show how hard the development team worked on this. Happy Birthday CRS-3!

  2. Hi Pankaj,

    What about the CRS-3 “bit flipping” issue?

    The bit flip is an interesting phenomenon because the Cisco CRS-3 is rumored to have used Broadcom 3rd party silicon, which did not use ECC protected memory subsystems and did not use low-alpha particle lead.

    Normal lead occasionally kicks out an alpha particle and with transistor densities being what they are today it can cause a bit to “stick” in a memory subsystem.

    This then causes the memory to corrupt and then pretty much snowballs into at least a minimum of having the ASIC being reset, and then possibly having an entire system reset.

    It happened most famously with the Cisco 4500 and 6500 and the Toshiba SRAMs back in the 2002-2004 time frame, causing tens of millions of dollars of hardware recall.

    Bottom line: There’s no real “field fix” in most cases and a line card swap out is called for.

    Didn’t Comcast and AT&T formally petition both Cisco and Broadcom about the issue because it caused network outages at both Comcast and AT&T?

  3. The strong market response to the CRS-3 validates our belief that this platform is the foundation for the next-generation Internet.

  4. It shouldn’t be a surprise that the CRS-3 is a success. It is the first of it’s kind in ultra high capacity carrier routing systems, in fact the two are synonymous at this point. It has definitely lived up to the hype unlike other nameless systems.
